Schroeder was appointed Southern Representative (New Orleans) for che promising, young Crocker-Wheeler F.lectric Company. He soon sensed the market developing in the infant steel area around Birmingham, Alabama, established headquarters therr, and began, what is to date, a 48-year hitch as "Mr. Crocker Wheeler' in and around Alabama. In 1912 he formed the General Machinery Company, broadening his product line to include, in addition to Crocker-Wher1cr motors--gears, motor control, mining machinery, wire rope, and other typ*s of equipment needed by the area's industry. Mr. Schroeder has had an active and in teresting career and is widely known and deeply respected throughout Alabama and nearby states. Devoted to sports and the outdoor life, he has been a pro ball player, hunter, yachtsman, deep sea fisherman, and aviator. He has owned three airplanes, surviving a serious crack-up in one of them. Although tapering off his business activities in recent years, *'B.A." still guides General Machinery Company and enjoys preaching the merits of his first love, Crocker-Wheeler motors.

THE modern coal preparation plant is a highly mechanized factory whose product is a better, more uniform fuel, free of impurities, dust, and dirt. The new plant of DeBardeleben Coal Corporation, Empire, Alabama, illustrated here, produces 1600 tons of the finest grade stoker coal every eight-hour shift. Many electric motors, predominately Crocker Wheeler, power the various process ing units. A wide variety of motor types are employed, including ordi nary open motors of normal charac teristics, totally-enclosed, fan-cooled Sealedpower designs, and high-torque motors. A battery of jig machines requires a high-slip motor with the highest starting torque that can be built into a squirrcl-cage motor. The Elliott Crocker-Wheeler motors in service in this plant range from 125 hp down to 10 hp. DeBardeleben Coal Corporation is one of the largest independent coal companiesinthcSouth.

A recent issue carried an interesting story of how an Elliott C-W brake motor was applied to very good advantage on a loom. We quote: "The William T. Carson Co., Philadelphia, had been vexed by a problem in their manufacture of zipper tape. Zipper tape must be woven to rigid specifications and when there are `stop-marks,' these sections must be cut from the tape. "These `stop-marks' are imperfections that are caused when the power is shut off on a narrow fabric loom, and the loom coasts to a stop as it does in four or five revolutions. "While it is coasting the batten does not pound the yam into the tape with its full power. This leaves a loose weave or imperfection that shows up plainly as a `stop-mark.' "You begin to realize the size of the problem when you learn that a loom is stopped for a variety of reasons--a broken thread, an empty bobbin--and the imperfections from each stop are multi plied because the loom is weaving 72 tapes at once. Hence each shutdown automatically produces `stop-marks' on every single one of the 72 rolls of tape. "How could these rejections be reduced? Lindsay-Oberholzer helped work out the solution, and the photographs of the converted loom drive indicate the way the following results were brought about. A major factor was the installation of a 1 -hp Elliott Crocker-Wheeler brake motor, which now stops the loom in less than one revolution instead of four or five. This change not only improv ed the quality of the tape, but also made it practical to increase the loom speed by five per cent, resulting in that much increased production per loom. "Another feature of the new installation was the application of a two-step \ -belt drive, which has resulted in longer belt life. , ``The cost of the new equipment amounted to about $200 per ">o:n. But the saving, says Mr. Carson, amounts per loom per year to over S500. Plus better quality tape." Two of the installations of EUiolt CrocherWheeler 1-hp brake motors on narrow fabric looms making zipper tape at the plant of William T. Carson Co.. Philadelphia, Pa. The brake motors eliminate "stop-markson the tape, and stop looms within one revolution.

A HOSPITAL DEAERATING HEATER INSTALLATION THIS neat installation of an Elliott 28,000-lb-per-hr vertical deaerating feedwater heater mounted on a hori zontal storage tank recently went into sen ice at the Swedish Hospital, Minneapolis, Minn. Installed by Bjorkman Bros. Company, of Minneapolis, the heater replaced a 40-yearold open-type heater, which had been moved from an old power plant into the new hospital building. The present power plant contains two 300-hp and one 412-hp boilers, and two 400-lcw steam engine-generators operating on ! 50 psi steam. Returns from the heating system are pumped directly into the heater, uncontrolled, by vacuum pumps. An internal float control governs a water make-up valve which admits city water when necessary. The heater was located at a higher elevation than the old heater to increase the sub_ mergence on the reciprocating boiler-feed pumps. A. H. Guetcholf, chief engineer, is very well pleased with the operation of the new heater ns compared w ith the old. He figures that he has increased the evaporation in the boilers from 8 to 8JA lb per 10,000 Btu, which results in a saving of 5.7 per cent on fuel, based on a normal winter's day oper ation of 430,000 lb of steam per day. Boiler feedwater temperatures average 212 F, as against 1~0 F with the old heater. The new healer has definitely eliminated oxygen corrosiun troubles in the boiler and steam piping.

Once set, this new Elliott lubricator requires no adjustment--no turning on or off. It is actuated entirely by pressure of the operating air or steam, not by flow. As long as pressure is sup plied, oil is accurately metered into the operating hose. When operating pressure is off, oil flow is shut off tight. The rate of oil flow is controlled by a knurled cap on top of the lubricator. The cap is backed off to increase flow, tightened to reduce it. Depending upon the tool to be lubricated, flow is normally set for from 25 to 50 drops per minute, as observed in the sight glass. Once adjusted, oil flow is ac curately maintained at the proper rate. In tube cleaner service, adjust ment is correct when a fine mist is observed at the motor exhaust. Oil is replenished by removing a knurled filler plug. The plug can be removed and reseated by hand, no further tightening being required for a leakproof fit. Although especially designed for tube cleaner service, the Elliott pres sure-type lubricator is suitable for many other types of air- or steampowered equipment. However, since its operation is based on pressure, not flow, a shut-off valve in the operat ing line must always precede the lubricator. It is therefore unsuited for use with tools which are con trolled at the motor. The new lubricator is supplied in two sizes--pint and quart capacities. is. a 'Jed. d to ugly This soft, ring lini.Vs n iar\ ALCOHOL INJECTOR This little device, consisting of a regulator and a sight-feed valve, is one of several made by our Lagonda tube cleaner division for a steel mill.

Potash salts have their largest use in the production of commercial fertilizer, potash being the "table salt" of the plant kingdom. Just as sodium chloride is necessary for the support of human life so also a certain amount of potassium salt is necessary if plant life is to exist. Part of the world production of potash is also used in the production of various potassium chemicals, such as potassium hydroxide, potassium permanganate, chlorates, chromates, and many others. These potassium bearing materials are used in the manufacture of soap, safety matches, This photograph shows the line of Elliott turbine-driven single-stage blowers serving continuousfilters in the Carlsbad plant.

The t in order to separate the potassium chloride from sodium chloride and other minor impurities present in the ore. The process used consists of a continuous dissolving step in which potassium chloride goes into solution in saturated brines heated to 225 F. These saturated brines are then cooled in continuous crystallizer units by boiling under a vacuum, which cooling causes the potassium chloride crystals to fall out of solu tion as a pure, white fine-grained salt. The slurry of crystals in saturated sodium chloride brine is then fed to top-feed Oliver filters where the brine is removed from the pure potassium chloride. A flow of air heated in gas-fired furnaces is drawn through the drums of these filters in order to remove the brine from potash crystals. The heated air also dries the thick residual cake of pure product as it revolves on the filter drum. The turbines. These blowers arc located on the suction side of the filters. The separated brine leaves a special trap and is returned again to the dissolv ing process. The air drawn from the trap is hot and saturated with moisture. Since the brines and mois ture in the air are highly corrosive, the blowers used by the United States Potash Company are equipped with special alloy impellers which are designed to withstand the diffi cult conditions encountered. The first Eliiotr-biower-equipped filter unit was installed in the original United States Potash Company's refinery in 1932 and has been oper ating on a continuous 24-hour-a-day. 363-dav-a-year schedule since that time.

This history-making event occurred at the National Reactor Testing Station in Idaho. Mechanical power to drive this generator was provided by a steam turbine. Steam was gen erated by heat energy removed from the experimental breeder reactor by liquid metal circulated through the reactor, as diagrammed above. / his Elliott 300-kw l2UU-rpm generator was the medium through which flowed the first kilowatts ever to be generated by atomic power. The geared turbine-generator is exactly the same as would be used in a conventionalfuel-fired steam plant. The light bulbs in this photograph were used to illustrate graphically thefirst known use of electrical powerfrom atomic energy on December 20, 1951. filext day power was increased to a point where the entire building was supplied by power emanating from the atomic reactor. ooo 000 I REPOWERED TUG SETS SERVICE RECORD ITERA1.LY thousands of Elliott "In less than two years since the United States equipped wit turbochargers are in sen-ice in installation of a 1750-hp Nordbcrg slow-specd, heavy-duty diesel cn all sorts of applications of four-cycle diesel engine, the tug Titan, owned directly connected to the prop diesel engines, on locomotives, ships, and operated by the Sabine Towing shaft.

"Shprtlv after her shakedown cruise in 1949, the Titan was called upon to demonstrate her new-found power. A large 15,000-ton tanker, fully loaded, experienced engine troubic off Sabine, Texas. The Titan went out to bring the ship in, but the owners of the tanker wanted the ship in Philadelphia and so the Titan headed east with her in tow. The 1500 miles were made at an average speed of ~V> knots. "In September of 1950, when the tail end of a hurricane hit the Louisiana coast, a large seagoing derrick barge, which was Ix'ing used ir. offshore drilling operations by >ne ol the major companies, was lx ng lowed to a port of refuge. This derrick barge had a crew of some ten men on board and she went adrift. The Coast Guard did not have a vessel available for her rescue, none of the harlxir tugs would venture out 'nto the teeth of this hurricane, so the Sabine Towing Company was asked to send the Titan to make the rescue. The Titan, under command of Captain H. G. MeElwee. a veteran of many years of ocean towing service with this company, put out to sea and with the aid of radar and wireless telephone, after some 24 hours of search, the derrick barge was located and through skillful sea manship and maneuvering a hawser was put on board and. finally, the derrick barge brought to a safe port of refuge. This is only one of several salvage operations that the Titan has performed during the hurricane season since Ixring commissioned. "The tug has been showing its muscles ever since. For many months last year it was active in moving Liberty and Victory-type cargo ships front the preparation area around Orange and Houston, Tex. to the storage area near New Orleans, La. Since the fall of 1950, the Titan has been lowing a 40,000-barre! ocean barge back and forth between Houston and Jacksonville." The lug Titan was originally built in 1912. A coal-burning tug fitted with a triple-expansion steam engine, it was used in the construction of the Panama Canal. In 1923, it was sold to the Sabine Towing Company, was converted from coal to oil, and put into coastwise and ocean towing in the Gulf of Mexico and up the Atlantic seaboard. In 1949, the steam plant was re placed with a Nordlierg turbocharged diesel engine--1750 shp at 327 rpm. This engine is not only the main propulsion unit but part of the engine power at the shaft can be used to drive a 120-volt, 80-amp generator. In addition to the Elliott turbo charger which serves the engine, the lubricating oil system includes an Elliott twin strainer. As the Titan was rebuilt in mak ing this change or power plant, great care was exercised to insure that the highly-powered, modernized tug would retain its excellent character istics of balance and trim. The Sabine Towing Company, Inc., which was founded in 1909, is an extensive organization. It operates five harlxir tugs, three coastwise tugs (of which the Titan is one), and 12 intcrcoastal tugs, as well as many barges and a Heel of oil tankers. ismKiirtx, sen ini issz PAGE EXTRACTION TURBINE CUTS POWER COSTS, BOOSTS PLANT PRODUCTION by JOHfl BALLA, Plant Engineer, Allen B. tVrisley Com Glass brick was extensively used in the construction of this strikingly modern Chicago plant of the Allen B. H'risley Company, where some of the country's finest quality soaps and cosmetics are manufactured. WHEN the management of Allen B. W'ri Company, Chicago, planned a major expans back in 1945, one of the first considerations 1 modernization of the power plant. The VVrisley Company, which manufactures st and cosmetics, requires steam for process use as v as for electric generation. Formerly, plant pov was provided, inefficiently and expensively, by t reciprocating steam engines supplemented by diesel generator. Steam for both the steam engit and several production processes had been suppli at 185 psi. The plant expansion program, however, promis a heavier process-steam load plus need for addition electric power. Solution to both problems was fout in the installation of an Elliott extraction turbin generator unit. First step in modernization was ; increase boiler efficiency through the use of model automatic controls, rigid control of boiler wate and an extensive metering program. Steam pressur was increased to 200 psi, some 80 to 90 per cent c this steam going directly to the 1500-kw Elliott ex traction turbine, the balance being used in plan processes requiring high-pressure steam. Steam fo other processes is extracted from the turbine a 100 psi. The 5 psi exhaust steam is also employee in process work as well as for heating and ait conditioning. Not only does this system wring every last Btu from the steam, but it was found that increasing pressure from 185 psi to 200 psi on a number of processing units boosted their production at com paratively little extra cost. Since instaliation of the 1500-kw Elliott turbinegenerator, there has been no further need to pur chase outside pover to supplement the plant capacity. This, together with the improved pro duction possible with higher pressure steam, has resulted in significant savings. To date, the Elliott turbine has been operating for more than five years, night and day, seven days a week, with no trouble whatsoever. ^AGE 24 l*U\VEHFAX.

The power output is presently sold to Georgia Power Company. The lake created by the dam has a shore line of 260 miles at the top of the flood control pool, and 180 miles at the top of the power pool. It is becom ing increasingly popular as a week end recreational area featuring boat ing, duck hunting, and fishing. The dam rises 190 ft above the river bed and has a total length at roadway level of] 250 ft. Two hydro-generators, having a total capacity of 72,000 kw, arc installed. A 2000-kw house turjine-generator unit provides auxiliary current, and supplys water for down stream users when the other units are not running. An interesting feature of the raw water system, which supplies cooling water for the generator stator, bear ings, and wearing rings is the use of Elliott self-cleaning strainers, which operate continuously and automati cally, and require no manual clean ing. They are located in the basement of the power plant and are connected directly off the main intake water headers.

But the I contemplated addition of four new I locomotives threatened to increase peak loads some 20 per cent, making 1 it necessary to increase the generating facilities. Gibbs and Hill, Inc. were j employed in 1946 to rehabilitate the plant including any additions re quired. An extension to the existing piant was built and a new 200,000Ib-per-hr boiler with accessories and complete pulverized-coal-firing equipment was installed, along with a new 10,000-kw turbine-generator. The turbine room extension also ac commodated the Elliott deaerating feedwater heater, the boiler-feed pumps, driven by Elliott motors and turbine, and Elliott water strainers, all illustrated here. Installation of the new boiler and turbine and rehabilitation of the old equipment has greatly improved the over-all performance of the Narrows Plant, making it possible to handle the increased demand imposed by new electric propulsion equipment and heavier hauls. Two oj the three boiler-feed pumps installed with the new boiler are driven by Elliott 350-hp, 25-cycle dripprooj "Fabri-Steel" motors, through reduction gears {above).
